Daz Black rectangle in render (it's not a spotlight with render emitter on)

[lawfullame]

Any idea why there is the black rectangle at the top of the render?
Sometimes it helped to restart Daz Studio, but in this case I can't get rid of it.
It's not a spotlight with render emitter on.
EDIT: I've found that the glitch goes away when I turn off one of the lights or turn the camera a little to the side. That bug is probably related to the combination of the camera position and the position of my ghost lights. But the camera does not intersect any objects.
